Q. India's Nuclear Energy Mission and the push for Small Modular Reactors represent a paradigm shift in the country's energy security strategy. Critically examine the opportunities and challenges involved. (15 marks, 250-350 words)

India's nuclear sector, a state monopoly since the Atomic Energy Act, 1962, is being restructured. Budget 2025-26's Nuclear Energy Mission commits ₹20,000 crore to SMR R&D, targeting five indigenous SMRs by 2033 and 100 GWe by 2047 [1]. The shift in strategy is real, but presently enabling rather than accomplished.

Opportunities - Firm low-carbon baseload: SMRs (up to 300 MW) supply dispatchable power that complements variable solar and wind, anchoring the 100 GWe-by-2047 pathway to Net Zero 2070 [1]. - Industrial decarbonisation: BSMR-200 can repurpose retiring thermal plants and serve energy-intensive industry; SMR-55 targets remote, off-grid demand; a 5 MWth HTGR at Vizag is designed for hydrogen generation [2]. - New commercial model: NPCIL's RFP for 220 MW Bharat Small Reactors lets private industry provide land, cooling water and capital while NPCIL retains design, quality assurance and O&M [3]. - Legal unlocking: the SHANTI Act, 2025 replaced the Atomic Energy Act, 1962 and CLNDA, 2010 — licensing Indian private companies and public-private JVs, and replacing the flat liability cap with graded operator liability of ₹100–3,000 crore [4]. Investor response is visible in the Fairwood Nuclear–SK Securities pact (June 2026) for SMR/MMR development and financing [5].

Challenges - Foreign participation still restricted: SHANTI bars companies incorporated outside India from licences, so overseas partners enter only as financiers or vendors — constraining capital and technology inflow [4][5]. - Fuel-cycle bottleneck: enrichment, reprocessing, spent-fuel and heavy-water functions remain exclusively governmental, limiting private scalability [4]. - Delivery risk: BSMR construction alone is estimated at 60–72 months after approval, leaving little slack against 2033 [3]. - Unproven economics and regulatory load: modular cost advantages depend on serial orders; dispersed siting multiplies safety, waste and public-acceptance demands on the statutorily recognised AERB [4].

The Mission genuinely reorients India from a few large state reactors towards distributed, industry-facing nuclear power. Sequencing regulatory capacity-building with the first BSR orders, and revisiting the foreign-equity bar as the framework matures, will determine whether legislative intent converts into installed capacity.
